Suppose:
$ VAR="Bash Scripting"
Now to find the length of the above string, I have found 3 different ways:
$ echo "${#VAR}"
14
$ expr length "$VAR"
14
$ echo $VAR | awk '{print length}'
14

Thanks for this. It's always nice to see a few different ways of doing something.
how about echo -n $VAR | wc -m?
@Tyzoid D, thanks a lot.
